3?ECIFICATION forming part of Letters Patent No. 303,497, dated August 12, 1884.

Application filed April 19, 1884.

T0 at whom it rrtay concern.-

Be it known that I, HENRY DEOKMANN, a citizen of the United States, residing at Hudson, in the county of Steuben and State of Indiana, have invented a new and useful Traction-Engine, of which the following isa speciiication, reference being had to the accompanying drawings. I

This invention has relation to traction-engines for use on roads or in fields for any of the purposes to which traction-engines are applicable; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

Figure 1 is a view in perspective of a traction-engine embodying myimprovements, one of the front wheels being broken away. Fig. 2 is a bottom view. Fig. 3 is a vertical longitudinal sectional view on thelinex' w inFig. 2. Fig. at is a vertical longitudinal sectional View on the lineyyin Fig. 2. Fig. 5 is atransverse vertical sectional view taken through the line of the front axle. Fig. 6 is a detail view of the central vertical miter-gear on the front axle. Fig. 7 is a detail View of the sleeve on the front axle, shown detached and the wheel removed from said sleeve. Fig. 8 is a bottom view of the turn-table. Fig. 9 is a plan view of the same, the boiler being removed. Fig. 10 is a detail view of the pinion detached from the inner end of the sleeve.

Referring by letter to the accompanying drawings, a and a designate the front wheels of the traction-engine. The axle a for these two wheels is a rotary axle,which is provided near one end with a fixed flanged collar, a provided with pin holes a" a" through its flange, at diametrically-opposite points, for the reception of the key-pins a a which pass through horizontal holes in the hub of the wheel a, to secure to and cause it to revolve with the axle a The wheel a is secured to a flange, a, on the outer end of a sleeve, to, in a manner similar to that just described for attaching the wheel a to the collar a, so that the axle a will revolve in the sleeve (0 in turning. Linchpins are also used at the ends of the axle to support the wheels in case of breakage of the key-pins. The axle a and sleeve a have their bearings in the lower ends of the (N0 model.)

brackets bib in boxes, the lower halves of which are bolted onto the brackets. Immediately beneath these half-boxes, and secured in place by the same bolts or screws that fasten The flange c of the plained. The base 0 is provided with a central opening for the passage of a vertical journal, 0, on the under face of the top section, (I, of the turn-table. The top section,

- d, of the turn-table consists of an annularcasting having a closed bottom, except at its center, where an opening for a vertical shaft, (1, is provided. Bearings cl are cast in its bot-- tom for the reception of friction-rollers d, which are cast integral with their journals,

and are let into their recessed bearings, their 7 5 peripheries just protruding sufficiently from the recesses to travel on the base a of the turntable-that is, to revolve when the base a is turnedand thereby lessen the frictional contact between the top and base. tion, (I, is provided with a peripheral flange, e, which rests on the vertical flange of the base, and the shoulders of guide-arms e e, secured to the base-section c, engage the upper face of the peripheral flange e, to guide thes frictional surfaces of the two sections in parallel planes when the base-section is turned either to the right or to the left. The axle a is provided with an enlargement, f, at that The top sec 80 side of its middle nearest the wheel a, and

the inner end of this enlargement f is provided with a half-clutch, f, which engages a half-clutch, J, on the plane face of .a miterpinion, f, on the axle. The teeth of this smaller 1niter.-pinions, g g g, journaled radially in radial recesses g g g in the hub of a larger miter-gear wheel, 9, at the middle of the axle (L The teeth of the 'miter -gear Wheel g are on the right face of its rim. The 100 left face of the miter-gear wheel 9* is dished, and the teeth of the three small miter-pinions 'miter pinion f engage the teeth of three g g project also slightly from that face and engage the teeth of a miter-pinion, h, which is connected by clutch-pins to the flange h at the inner end of the sleeve a. the front axle and the gearing attached to it. The rear axle is an ordinary axle, on which the wheels turn in the usual manner. The miter-gear wheel 9" on the middle of the axle a? meshes with a miter-pinion, i, on the lower end of the vertical shaft d, which passes up through the vertical journal 0 on the under face of the top section, (I, of the turn-table. At the upper end of the vertical shaft d is a transverse bearing-bar, i, secured in the inner walls of the annular top section, in which the shaft (1 is journaled. Below this bearingbar the vertical shaft (1 is provided with a miter-gear wheel, 7?, having its teeth upon its upper face. This miter gear wheel i meshes with a miter-pinion, i", on the shaft i, which is journaled in hearings in the top section, (I, of the turn-table, above the transverse bearing-bar z" and at right angles thereto. This shaft 13" extends rearward from the top section, d, and is provided at its rear end with a loose coupling-sleeve, i The top section, 01, is provided at its left side over the cog-teeth c with a double bearing-bracket, 70, having ver tical bearings 7c and horizontal bearings k". This bracket is provided with a vertical shaft, Z, upon the lower end of which is fixed a cogpinion, Z, which meshes with the cog-teeth c on the flange-rim of the base-section c. At the upper end this shaft Z is provided with a miter-pinion, Z", which meshes with a miterpinion, m, on the end of a horizontal shaft, m, journaled in the bearing 7c". The rear end of this shaft m is provided with a loose coupling-sleeve, m". The upper face of the top section of the turn-table is provided at the front and rear of the annular casting with recesses n a, which, together with the slotted capplates or a, form sockets for the heads a 31 for the oscillating standards 0 0, to which the forward end of the boiler 0 is secured. To the rear wall of the fire-box p is secured a double bracket, 1), having longitudinal and lateral bearings for the gearing, to be now explained.

The horizontal shaft g, which extends longitudinal of frame of the engine, is coupled by a loose coupling, i to the rear end of the shaft '6". The rear end of the shaft q'is provided with a miter-pinion, g, which meshes with a miter-pinion, q", 011 the inner end of a horizontal shaft, r, at right angles to the shaft q, and the outer end of this latter shaft, r, is provided with a cog-pinion, which receives the power from the engine and transmits it to the gearing within the turn-table, and thence to the gearing on the front axle, and through the latter to the wheels a a. From the left side of the fire-box extends an arm, 3, which forms the rear bearin g for the horizontal steering-shaft s, the forward end of which is coupled to the rear end of thehorizontal shaft m by a loose coupling-sleeve W. The rear end of the steering-shaft s is provided with a hand-wheel,

This completes 3', which is in easy reach of the engineerat the door of the furnace, so that by turning the hand-wheel in the proper direction he can turn the base-section of the turn-table either to the right or left, or hold it straight, or at any intermediate position between its right and left limits, and thus guide and turn the .front wheels to cause the engine to travel in any desired direction. By reversing the en gine the machine can bemoved backward, and may by the instrumentality of the steering mechanism be guided with absolute certainty in its backward movement.

This engine can be made of any desired weight, and is strong and durable in all of its parts. It can be made to travel over rough or uneven roads and up and down inclines 1. In a traction-engine, the combination,
